The actor and star of spoof rock band Tenacious D is claimed to have died on the band's official Twitter account, though the statement has come under question after the band's Facebook page and website failed to reflect the show.

And now with the rumours of his death swirling, and no word from any of the star's reps, concerned fans have begun posting video and pictures from what could be Black's final performance.

The star took to the stage at Germany's Rock in the Park festival on Saturday night with fans posting footage of the performance on social media.

It comes after Black was pictured partying with producer Diplo just hours before his "death" was alleged in a message on the official Tenacious D Twitter account.

Fans on Sunday morning have been left confused by tweets from the duo's account claiming the actor died at 3:17am. But around a similar time, he appeared on the US musician's SnapChat as they posed together for a picture in the early hours of Sunday morning.

Showing a stamp of "9 hours ago" at around 11:30am GMT, around the same time the death occurred according to the tweets.

Jack looked in pretty good spirits as he posed next to the producer outside a hotel lobby.

The photo appears to have been taken at Rock Am Ring festival in Germany where the producer performed last night and Jack, with Tenacious D on Friday.

If Jack has died, Diplo showed no sign of it on Sunday morning where he posted photos from the performance.

A message posted on Tenacious D's official Twitter page - which included a spelling error - on Sunday claimed: "I'm sad to officially annouce the death of Jack Black at the age of 46, rest in peace brother." (sic)

It was followed five minutes later by: "#RipJackBlack"

A further tweet an hour later claimed: "It is with a heavy heart I am to announce that Jack Black passed away last night at 3:37am. The cause of death is yet unknown."

It's unclear if the account for the singing duo, of which Jack makes up one half along with Kyle Gass, has been hacked, something most fans suspected after seeing the messages.

Jack was seen in public just two days ago, when the group performed at Rock Am Ring festival in Germany on Friday night.

Mirror Celeb have contacted reps for the star to establish the validity of the claims.

It's not the first time the Hollywood joker has been the victim of a death hoax. Earlier this year a rumour went around the internet that he had passed away, but was traced back to a hoax site. The same thing happened two years ago as well.

Fans weren't convinced by the message, with one writing: "That's about the 4th time Jack Black has died."

"Has the internet killed Jack Black again?" someone else asked.

Others hit out at the message, claiming it was in poor taste.

This fan wrote: "If this Jack Black news is a practical joke or a hack then it's a really low act."

Some even thought it could by Jack and Kyle playing tricks on their fans: "is jack black hiding under his bed giggling"

With the string of celebrities deaths in 2016, others seemed to hope it was just a tasteless joke.

Another tweeter added: "...please tell me this Jack Black thing is a hoax"
